SCLEROTINIA.

leaves of Vt-riit iii 111 r///.s- /</">" exhibit in sprini: a m>ulil- 

 like coating, con-i-ting of chains of lemon-shaped conidia. 



\V'>ronin thus describes it: "In tin.' nutt-r layers of tin- cortex, 

 amongst the dying elements, a pseudoparenchymatoiis cu.-hion i> 

 tormed, from \vhich simple or dichotomously branched hyphae 

 jrow nut through the overlying cuticle. The individual menilicrs 

 of the chains of conidia are separated from one another by a 

 spindle-shaped piece of cellulose 'the disjunctor.' ' 



The disjunctor spoken of here is a spindle-shaped cellulose 

 l>ody i'mind lift ween the single conidia; it easily Invaks across 

 and so facilitates the breaking up of the chains of conidia
